# 3DMolecule vs Functional Groups

The clearest difference is in-app purchases: 3DMolecule at none against Functional Groups's 1. Functional Groups's advantage is ratings volume (23 vs 2). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Functional Groups sells 1 one-off in-app purchase. 3DMolecule asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for 3DMolecule against 4.9 for Functional Groups. That said, the two scores are not equally well evidenced: Functional Groups has 23 ratings behind it against 2, so its average is the more settled of the two.
